Le développement de l'agriculture organique au Brésil prend des formes multiples. Au travers de leur expérience de l'AO, dans une communauté proche de trois métropoles, de petits maraîchers d'Ibiúna (São Paulo) créent des entités collectives et expérimentent de nouvelles pratiques sociales.
Biotechnology offers great potential to contribute to sustainable agricultural growth, food security and poverty alleviation in developing countries. Yet there are economic and institutional constraints at national and international levels that inhibit the poor people's access to appropriate biotechnological innovations.
The topics addressed in this book are of vital importance to the survival of humankind. Agricultural biodiversity, encompassing genetic diversity as well as human knowledge, is the base upon which agricultural production has been built, and protecting this resource is critical to ensuring the capacity of current and future generations to adapt to unforeseen challenges.
Local innovation refers to the dynamics of Indigenous Knowledge (IK) - the knowledge that grows within a social group, incorporating learning from own experience over generations but also knowledge gained from other sources and fully internalized within local ways of thinking and doing. Local innovation is the process through which individuals or groups discover or develop new and better ways of managing resources - building on and expanding the boundaries of their IK.

Farmers in Asia like to grow cassava because the crop will tolerate long dry periods and poor soils, and will produce reasonable yields with little inputs. Most farmers realize, however, that cassava production on slopes can cause severe erosion, while production without fertilizer inputs may lead to a decline in soil productivity. Research has shown that cassava yields can be maintained for many years with adequate application of fertilizers, and that there are various ways to reduce erosion.
Ce texte présente les premiers résultats d’une étude sur la contribution de groupes d’agriculteurs familiaux aux processus d’innovation dans trois municipes de la Paraíba (Brésil). L’objectif consistait à identifier le rôle des producteurs et de leurs organisations en matière d’introduction et d’adaptation de techniques agricoles.
Global adoption of transgenic crops reached 67.7 million hectares in 2003 from 2.8 million in 1996. Delivery has occurred almost entirely through the private sector and adoption has been rapid in areas where the crops addressed serious production constraints and where farmers had access to the new technologies. Three countries (USA, Argentina and Canada), three crops (soybean, cotton and maize) and two traits (insect resistance and herbicide tolerance) account for the vast majority of global transgenic area.
Para preparación de este documento se llevó a cabo una consulta con los actores de la producción orgánica en las diferentes regiones del país, tratando de identificar desde su perspectiva, las limitaciones y potencialidades que presenta la actividad, así como las áreas estratégicas sobre las cuales se debe incidir para favorecer el desarrollo de la misma. El análisis de la información recabada permitió elaborar una propuesta de estrategia para el desarrollo de la actividad la cual, entre otros, contiene políticas y acciones alrededor de las mismas.
The increasing complexity of technology development and adoption is rapidly changing the effectiveness of scientific and technological policies. Complex technologies are developed and disseminated by networks of agents. The impact of these networks depends on the assets they command, their learning routines, the socio-economic environment in which they operate and their history.
This presentation from the 2nd Triennial GFAR Conference, held in Senegal in 2003, presents InterSard and InterDev: two cases of partnerships for sharing information and knowledge on good practices and local innovation.
